1. Lucas Oil 10879 White Lithium Grease: Best Overall for Suspension Bushings
In our evaluation of suspension greases, Lucas Oil 10879 stands out for its balanced performance. Based on owner feedback and the spec sheets, this lithium complex grease provides excellent adhesion to metal and rubber surfaces, reducing squeaks and wear on bushings, ball joints, and tie rod ends. Its high dropping point ensures it stays put even during spirited driving or off-road use. Many owners report it outlasts lower-cost greases by a wide margin.
However, this grease is not ideal for applications requiring extreme low-temperature flexibility, as it can thicken in very cold climates. If you live in subzero conditions and need a grease that stays soft, consider a synthetic alternative. Also, it should not be used in sealed wheel bearings that require a specific NLGI #2 EP grease. For most suspension maintenance, this is a reliable choice.
- Excellent adhesion and water resistance for suspension bushings and ball joints
- High dropping point (over 400°F) reduces melting in heavy use
- Works well on rubber and metal components without causing swelling
Pros: Long-lasting lubrication even in wet conditions; Adaptable for multiple suspension points
Cons: Not recommended for high-speed wheel bearings
2. WD-40 Specialist Silicone Lubricant: Best for Rubber Bushings and Seals
WD-40 Specialist Silicone Lubricant is a top choice for rubber suspension components like control arm bushings, sway bar bushings, and CV boot seals. Based on owner feedback and the spec sheets, this silicone spray does not degrade rubber or attract dirt like some petroleum-based products. It also provides a dry film that reduces squeaks and protects against freezing. Many users appreciate the easy spray application for hard-to-reach areas.
However, this lubricant is not suitable for high-load metal joints such as ball joints or tie rod ends where a thicker grease is required. It will quickly wear off under heavy pressure. If you need a lubricant for metal-on-metal suspension parts, choose a grease instead. For rubber maintenance and noise elimination, this is an effective and convenient option.
- Non-staining, clear formula safe for rubber and plastic
- Reduces friction and noise on door seals, bushings, and suspension boots
- Spray applicator reaches tight spots easily
Pros: Excellent for lubricating rubber components without damage; Very easy to apply with precision straw
Cons: Not a heavy-duty grease for metal-on-metal suspension joints
3. CRC 5037 White Lithium Grease: Best Value for General Use
CRC 5037 is a solid, budget-friendly white lithium grease that performs adequately for general suspension lubrication. In our research, owners report it reduces squeaks on sway bar bushings and stabilizer links, and it holds up well in normal driving conditions. The aerosol can makes application clean and easy, and the grease adheres well to metal surfaces. For the price, it offers decent water resistance and rust prevention.
However, this grease has a lower dropping point than premium options, meaning it may melt and run off in high-heat situations like track days or heavy towing. It also tends to stiffen in cold weather. If you drive in extreme conditions or need a grease that lasts longer between applications, consider upgrading to a synthetic or lithium complex product. For routine maintenance and light use, it’s a fine choice.
- Affordable price for a large can, good for multiple applications
- Provides good lubrication for suspension bushings and chassis points
- Resists water washout and corrosion
Pros: Great value for budget-conscious buyers; Works well on a variety of suspension components
Cons: Not as durable as synthetic greases in extreme heat
4. Permatex 22058 Dielectric Tune-Up Grease: Best for Electrical Connections in Suspension Systems
Permatex 22058 is a specialized dielectric grease designed for electrical connections, but it has a place in suspension maintenance. Modern suspension systems often include sensors (height sensors, ABS rings) and connectors that can corrode. Based on owner feedback, applying this grease to connectors prevents moisture and oxidation, ensuring reliable signal transmission. It is also safe on rubber boots and seals.
However, this product is not a lubricant for moving suspension components like ball joints or bushings. It should not be used as a substitute for grease. If you are looking for a lubricant to reduce friction, this is not the right pick. But for protecting electrical parts in your suspension system, it is highly effective.
- Protects electrical connectors in suspension sensors and wiring
- Non-conductive, prevents corrosion and moisture ingress
- Safe on rubber and plastic components
Pros: Excellent for sealing and protecting electrical connections; Long-lasting protection against corrosion
Cons: Not a general-purpose lubricant for moving suspension parts
5. LubriMatic 11314 Multi-Purpose Grease: Good for Older Suspension Systems
LubriMatic 11314 is a conventional multi-purpose grease that is best suited for older suspension systems that have grease fittings. In our research, owners of classic cars and trucks appreciate its compatibility with standard grease guns and its ability to lubricate ball joints and tie rod ends adequately. It provides decent protection against rust and wear for normal driving.
However, this grease lacks the high-temperature stability and water resistance of modern synthetic greases. It can break down under heavy loads or in wet conditions, leading to more frequent reapplication. If you drive off-road, tow, or have a performance vehicle, you will likely need a more solid product. For occasional use on older vehicles, it gets the job done.
- Compatible with standard grease guns for easy application
- Provides adequate lubrication for chassis and suspension fittings
- Good for older vehicles with grease fittings
Pros: Works well with grease guns for precise application; Suitable for classic cars with zerk fittings
Cons: Not recommended for high-performance or heavy-duty use
6. Super Lube 21030 Synthetic Grease: Best for Smooth Operation and Noise Reduction
Super Lube 21030 is a premium synthetic grease that excels at reducing friction and noise in suspension components. Based on owner feedback and the spec sheets, its PTFE (Teflon) formulation provides a slick film that lasts longer than conventional greases. It is especially effective on sway bar bushings, control arm bushings, and stabilizer links. The wide temperature range makes it suitable for both cold winters and hot summers.
The main downside is its cost; it is more expensive than most other greases in this guide. However, for those who want the best performance and are willing to pay for it, this is a top-tier choice. It is not ideal for high-speed wheel bearings that require a specific EP additive, but for suspension components it is excellent. If you are on a tight budget, you may prefer a more affordable option.
- Ultra-smooth synthetic formula reduces friction and noise
- Excellent temperature range for extreme climates
- Non-toxic, odorless, and safe on rubber and plastic
Pros: Outstanding noise reduction on bushings and joints; Works in very low and high temperatures

Frequently Asked Questions
What type of lubricant is best for suspension bushings?
For rubber bushings, a silicone-based lubricant is often safest as it does not degrade rubber. For polyurethane bushings, a lithium complex grease or synthetic grease with PTFE works well. Always check the bushing material and manufacturer recommendations.
Can I use WD-40 on suspension parts?
Standard WD-40 is a solvent and light lubricant, not suitable for long-term suspension lubrication. It can be used to free rusted parts but should be followed by a proper grease. WD-40 Specialist Silicone or White Lithium are better choices for lubrication.
How often should I lubricate my suspension?
It depends on driving conditions and component type. For grease fittings, every oil change or 5,000 to 7,000 miles is common. For bushings, apply when you hear squeaks or during annual maintenance. Heavy off-road use requires more frequent lubrication.
Is white lithium grease good for ball joints?
White lithium grease can be used on ball joints, but it may not last as long as a lithium complex or synthetic grease under heavy loads. For most passenger cars, it is adequate if reapplied regularly. For performance or heavy-duty use, choose a grease with extreme pressure additives.
Can I use the same grease for suspension and wheel bearings?
Not always. Wheel bearings often require a high-temperature grease with EP additives (NLGI #2 with moly or lithium complex). Some greases are labeled multi-purpose and work for both, but always check the manufacturer’s specification for your vehicle’s wheel bearings.
